Constructor Detail

FlagsAttributeImpl

public FlagsAttributeImpl()
Method Detail

getFlags

public int getFlags()

Get the bitset for any bits that have been set. This is completely distinct from TypeAttribute.type(), although they do share similar purposes. The flags can be used to encode information about the token for use by other TokenFilters.

Specified by:
getFlags in interface FlagsAttribute
Returns:
The bits

setFlags

public void setFlags(int flags)
Specified by:
setFlags in interface FlagsAttribute
See Also:
getFlags()

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)
Overrides:
equals in class Object

hashCode

public int hashCode()
Overrides:
hashCode in class Object

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:
copyTo in class AttributeImpl
