getAdditionalFlags

public int getAdditionalFlags()

Description copied from class: CompletionProposal

Returns the completion flags relevant in the context, or CompletionFlags.Default if none.

This field is available for the following kinds of completion proposals:

• FIELD_IMPORT - completion flags of the attribute that is referenced. Completion flags for this proposal kind can only include CompletionFlags.StaticImport
• METHOD_IMPORT - completion flags of the attribute that is referenced. Completion flags for this proposal kind can only include CompletionFlags.StaticImport
• TYPE_IMPORT - completion flags of the attribute that is referenced. Completion flags for this proposal kind can only include CompletionFlags.StaticImport

For other kinds of completion proposals, this method returns CompletionFlags.Default.

Overrides:

getAdditionalFlags in class CompletionProposal

Returns:

the completion flags, or CompletionFlags.Default if none

See Also:

• CompletionFlags

setAdditionalFlags

public void setAdditionalFlags(int additionalFlags)

Description copied from class: CompletionProposal

Sets the completion flags relevant in the context.

If not set, defaults to none.

The completion engine creates instances of this class and sets its properties; this method is not intended to be used by other clients.

Overrides:

setAdditionalFlags in class CompletionProposal

Parameters:

additionalFlags - the completion flags, or CompletionFlags.Default if none

getKind

public int getKind()

Description copied from class: CompletionProposal

Returns the kind of completion being proposed.

The set of different kinds of completion proposals is expected to change over time. It is strongly recommended that clients do not assume that the kind is one of the ones they know about, and code defensively for the possibility of unexpected future growth.

Overrides:

getKind in class CompletionProposal

Returns:

the kind; one of the kind constants declared on this class, or possibly a kind unknown to the caller

getCompletionLocation

public int getCompletionLocation()

Description copied from class: CompletionProposal

Returns the character index in the source file buffer where source completion was requested (the offset parameter to ICodeAssist.codeComplete minus one).

Overrides:

getCompletionLocation in class CompletionProposal

Returns:

character index in source file buffer

See Also:

• ICodeAssist.codeComplete(int,CompletionRequestor)

getTokenStart

public int getTokenStart()

Description copied from class: CompletionProposal

Returns the character index of the start of the subrange in the source file buffer containing the relevant token being completed. This token is either the identifier or Java language keyword under, or immediately preceding, the original request offset. If the original request offset is not within or immediately after an identifier or keyword, then the position returned is original request offset and the token range is empty.

Overrides:

getTokenStart in class CompletionProposal

Returns:

character index of token start position (inclusive)

getTokenEnd

public int getTokenEnd()

Description copied from class: CompletionProposal

Returns the character index of the end (exclusive) of the subrange in the source file buffer containing the relevant token. When there is no relevant token, the range is empty (getEndToken() == getStartToken()).

Overrides:

getTokenEnd in class CompletionProposal

Returns:

character index of token end position (exclusive)

setTokenRange

public void setTokenRange(int startIndex,
 int endIndex)

Description copied from class: CompletionProposal

Sets the character indices of the subrange in the source file buffer containing the relevant token being completed. This token is either the identifier or Java language keyword under, or immediately preceding, the original request offset. If the original request offset is not within or immediately after an identifier or keyword, then the source range begins at original request offset and is empty.

If not set, defaults to empty subrange at [0,0).

Overrides:

setTokenRange in class CompletionProposal

Parameters:

startIndex - character index of token start position (inclusive)

endIndex - character index of token end position (exclusive)

getCompletion

public char[] getCompletion()

Description copied from class: CompletionProposal

Returns the proposed sequence of characters to insert into the source file buffer, replacing the characters at the specified source range. The string can be arbitrary; for example, it might include not only the name of a method but a set of parentheses.

The client must not modify the array returned.

Overrides:

getCompletion in class CompletionProposal

Returns:

the completion string

setCompletion

public void setCompletion(char[] completion)

Description copied from class: CompletionProposal

Sets the proposed sequence of characters to insert into the source file buffer, replacing the characters at the specified source range. The string can be arbitrary; for example, it might include not only the name of a method but a set of parentheses.

If not set, defaults to an empty character array.

The completion engine creates instances of this class and sets its properties; this method is not intended to be used by other clients.

Overrides:

setCompletion in class CompletionProposal

Parameters:

completion - the completion string

getReplaceStart

public int getReplaceStart()

Description copied from class: CompletionProposal

Returns the character index of the start of the subrange in the source file buffer to be replaced by the completion string. If the subrange is empty (getReplaceEnd() == getReplaceStart()), the completion string is to be inserted at this index.

Note that while the token subrange is precisely specified, the replacement range is loosely constrained and may not bear any direct relation to the original request offset. For example, it would be possible for a type completion to propose inserting an import declaration at the top of the compilation unit; or the completion might include trailing parentheses and punctuation for a method completion.

Overrides:

getReplaceStart in class CompletionProposal

Returns:

replacement start position (inclusive)

getReplaceEnd

public int getReplaceEnd()

Description copied from class: CompletionProposal

Returns the character index of the end of the subrange in the source file buffer to be replaced by the completion string. If the subrange is empty (getReplaceEnd() == getReplaceStart()), the completion string is to be inserted at this index.

Overrides:

getReplaceEnd in class CompletionProposal

Returns:

replacement end position (exclusive)

setReplaceRange

public void setReplaceRange(int startIndex,
 int endIndex)

Description copied from class: CompletionProposal

Sets the character indices of the subrange in the source file buffer to be replaced by the completion string. If the subrange is empty (startIndex == endIndex), the completion string is to be inserted at this index.

If not set, defaults to empty subrange at [0,0).

The completion engine creates instances of this class and sets its properties; this method is not intended to be used by other clients.

Overrides:

setReplaceRange in class CompletionProposal

Parameters:

startIndex - character index of replacement start position (inclusive)

endIndex - character index of replacement end position (exclusive)

Overrides:

setReceiverRange in class CompletionProposal

Parameters:

startIndex - character index of receiver start position (inclusive)

endIndex - character index of receiver end position (exclusive)

toString

public String toString()

Overrides:

toString in class Object

canUseDiamond

public boolean canUseDiamond(CompletionContext coreContext)

Description copied from class: CompletionProposal

Returns whether it is safe to use the '<>' (diamond) operator in place of explicitly specifying type arguments for this proposal.

This is only relevant for source level 1.7 or greater.

Overrides:

canUseDiamond in class CompletionProposal

Parameters:

coreContext - the completion context associated with the proposal

Returns:

true if it is safe to use the diamond operator for the constructor invocation, false otherwise. Also returns false for source levels below 1.7
