Method Detail

getPrologHandler

PrologHandler getPrologHandler()

Get the prolog handler for this clause.

Returns:

The PrologHandler this clause is using.

getExprFactory

ExprFactory getExprFactory()

Get the expression factory that works with the prefixes for this builder.

Returns:

an ExprFactory for this builder.

addPrefix

T addPrefix(String pfx,
            Resource uri)

Adds a prefix.

Parameters:

pfx - The prefix.

uri - The URI for the prefix

Returns:

This builder for chaining.

addPrefix

T addPrefix(String pfx,
            Node uri)

Adds a prefix.

Parameters:

pfx - The prefix.

uri - The URI for the prefix

Returns:

This builder for chaining.

addPrefix

T addPrefix(String pfx,
            String uri)

Adds a prefix.

Parameters:

pfx - The prefix.

uri - The URI for the prefix

Returns:

This builder for chaining.

addPrefixes

T addPrefixes(Map<String,String> prefixes)

Adds prefixes.

Parameters:

prefixes - A mapping of prefix to URI to add.

Returns:

This builder for chaining.

addPrefixes

T addPrefixes(PrefixMapping prefixes)

Adds prefixes.

Parameters:

prefixes - A PrefixMapping instance..

Returns:

This builder for chaining.

setBase

T setBase(Object uri)

Sets the base URI. See AbstractQueryBuilder.makeNode(java.lang.Object) for conversion of the uri param. The resulting Node must be a URI.

Parameters:

uri - The base URI to use.

Returns:

This builder for chaining.

setBase

T setBase(String uri)

Sets the base URI.

Parameters:

uri - The base URI to use.
