Constructor Detail

ValueOperatorPtg

public ValueOperatorPtg()

Method Detail

isBaseToken

public final boolean isBaseToken()

All Operator Ptgs are base tokens (i.e. are not RVA classified)

Specified by:

isBaseToken in class Ptg

Returns:

false if this token is classified as 'reference', 'value', or 'array'

getDefaultOperandClass

public final byte getDefaultOperandClass()

Overrides:

getDefaultOperandClass in class OperationPtg

write

public void write(LittleEndianOutput out)

Specified by:

write in class Ptg

getSid

protected abstract byte getSid()

getSize

public final int getSize()

Specified by:

getSize in class Ptg

Returns:

the encoded length of this Ptg, including the initial Ptg type identifier byte.

toFormulaString

public final java.lang.String toFormulaString()

Description copied from class: Ptg

return a string representation of this token alone

Specified by:

toFormulaString in class Ptg
