Method Detail

setParameter

public void setParameter(String name,
                         Object value)

Description copied from class: Phrase

Set parameter name to value.

NOTE: name is case insensitive.

Overrides:

setParameter in class Phrase

getStartOffset

public int getStartOffset()

Get the start offset (0 indexed, inclusive) for this term in the original query string.

This value is set during parsing and indicates the start offset into the original query string that this term represents. In general, offsets should not be set/modified by query transformers and it is recommended that start and end offsets are set to zero when cloning.

NOTE: if Phrase.getStartOffset() == Phrase.getEndOffset(), this indicates that the term did not come from a parsed query string.

Specified by:

getStartOffset in class Phrase

setStartOffset

public void setStartOffset(int value)

Set the start offset (0 indexed, inclusive) for this term in the original query string.

getEndOffset

public int getEndOffset()

Get the end offset (0 indexed, exclusive) for this term in the original query string.

This value is set during parsing and indicates the end offset of the original query string that this term represents. In general, offsets should not be set/modified by query transformers and it is recommended that start and end offsets are set to zero when cloning.

NOTE: if Phrase.getStartOffset() == Phrase.getEndOffset(), this indicates that the term did not come from a parsed query string.

Specified by:

getEndOffset in class Phrase

setEndOffset

public void setEndOffset(int value)

Set the end offset (0 indexed, exclusive) for this term in the original query string.

getAnnotations

public long getAnnotations()

Get all set token annotations as a bit mask.

Specified by:

getAnnotations in interface TokenAnnotationSet

setAnnotations

public void setAnnotations(long value)

Set the token annotations from a bit mask.

Specified by:

setAnnotations in interface TokenAnnotationSet

setAnnotation

public void setAnnotation(TokenAnnotation value)

Set a TokenAnnotation.

Specified by:

setAnnotation in interface TokenAnnotationSet

containsAnnotation

public boolean containsAnnotation(TokenAnnotation value)

Returns true if the specified annotation is set.

Specified by:

containsAnnotation in interface TokenAnnotationSet

unsetAnnotation

public void unsetAnnotation(TokenAnnotation value)

Unset a TokenAnnotation.

Specified by:

unsetAnnotation in interface TokenAnnotationSet

offsetGap

public int offsetGap(PhraseTerm previous)

Get the offset gap between previous and this term.

NOTE: if this term or the previous term do not contain offsets, 1 is returned.

NOTE: Returns 0 if previous is null.

containsParameters

public boolean containsParameters(boolean compact)

Does this phrase operand contain any parameters in a non-default state.

If compact is true this will only return true if at least one parameter in the compact representation of this phrase exists.

Overrides:

containsParameters in class Phrase

rewriteChildren

public Phrase rewriteChildren(PhraseHandler handler)

Description copied from class: Phrase

Rewrite any children of this phrase using handler.

Returns the modified phrase, which may be null if all children were removed by handler.

This method may have no effect if this Phrase represents a leaf in the tree.

NOTE: child phrases are not recursively traversed.

Specified by:

rewriteChildren in class Phrase

hashCode

public int hashCode()

Overrides:

hashCode in class Phrase

equals

public boolean equals(Object other)

Overrides:

equals in class Phrase
