Method Detail

type

public String type()

Returns this Token's lexical type. Defaults to "word".

Specified by:

type in interface TypeAttribute

setType

public void setType(String type)

Set the lexical type.

type()

clear

public void clear()

Description copied from class: AttributeImpl

Clears the values in this AttributeImpl and resets it to its default value. If this implementation implements more than one Attribute interface it clears all.

Specified by:

clear in class AttributeImpl

equals

public boolean equals(Object other)

Description copied from class: AttributeImpl

All values used for computation of AttributeImpl.hashCode() should be checked here for equality. see also Object.equals(Object)

Specified by:

equals in class AttributeImpl

hashCode

public int hashCode()

Description copied from class: AttributeImpl

Subclasses must implement this method and should compute a hashCode similar to this:

   public int hashCode() {
     int code = startOffset;
     code = code * 31 + endOffset;
     return code;
   }

copyTo

public void copyTo(AttributeImpl target)

Description copied from class: AttributeImpl

Copies the values from this Attribute into the passed-in target attribute. The target implementation must support all the Attributes this implementation supports.

Specified by:
