public class CreateImportOperation
extends CreateElementInCUOperation

This operation adds an import declaration to an existing compilation unit. If the compilation unit already includes the specified import declaration, the import is not generated (it does not generate duplicates). Note that it is valid to specify both a single-type import and an on-demand import for the same package, for example "java.io.File" and "java.io.*", in which case both are preserved since the semantics of this are not the same as just importing "java.io.*". Importing "java.lang.*", or the package in which the compilation unit is defined, are not treated as special cases. If they are specified, they are included in the result.

Required Attributes:

• Compilation unit
• Import name - the name of the import to add to the compilation unit. For example: "java.io.File" or "java.awt.*"

When executed, this operation will add an import to the given compilation unit.

Method Details

getChildPropertyDescriptor

protected StructuralPropertyDescriptor getChildPropertyDescriptor(ASTNode parent)

Specified by:

getChildPropertyDescriptor in class CreateElementInCUOperation

generateElementAST

protected ASTNode generateElementAST(ASTRewrite rewriter,
 ICompilationUnit cu)
                              throws JavaModelException

Specified by:

generateElementAST in class CreateElementInCUOperation

Throws:

JavaModelException

generateResultHandle

protected IJavaElement generateResultHandle()

Description copied from class: CreateElementInCUOperation

Creates and returns the handle for the element this operation created.

Specified by:

generateResultHandle in class CreateElementInCUOperation

See Also:

• CreateElementInCUOperation.generateResultHandle()

getMainTaskName

public String getMainTaskName()

Description copied from class: CreateElementInCUOperation

Returns the name of the main task of this operation for progress reporting.

Specified by:

getMainTaskName in class CreateElementInCUOperation

See Also:

• CreateElementInCUOperation.getMainTaskName()

initializeDefaultPosition

protected void initializeDefaultPosition()

Sets the correct position for the new import:

• after the last import
• if no imports, before the first type
• if no type, after the package statement
• and if no package statement - first thing in the CU

Overrides:

initializeDefaultPosition in class CreateElementInCUOperation

verify

public IJavaModelStatus verify()

Possible failures:

• NO_ELEMENTS_TO_PROCESS - the compilation unit supplied to the operation is null.
• INVALID_NAME - not a valid import declaration name.

Overrides:

verify in class CreateElementInCUOperation
