Method Detail

binaryCombineTypes

public Class binaryCombineTypes(Token operator,
                                Class accumType,
                                Class nextType)

Description copied from class: LeftAssociativeOperatorExpression

binaryCombineTypes -- Class of result of combining two types; implemented in subclasses

Overrides:

binaryCombineTypes in class LeftAssociativeOperatorExpression

Tags copied from class: LeftAssociativeOperatorExpression

Parameters:

operator - is the Token between expressions (e.g., +,-,*,/,...)

accumResult - is result of accumulating the expressions to the left of the operator.

nextResult - is result of evaluating the next expression to the right of the operator.

Returns:

Class of result of the combining accumResult and nextResult with operator.

Throws:

IllegalArgumentException - if types not acceptable

binaryCombine

public Object binaryCombine(Token operator,
                            Object accumResult,
                            Object nextResult)
                     throws ThrowException

Description copied from class: LeftAssociativeOperatorExpression

binaryCombine -- combine two values, implemented in subclasses

Overrides:

binaryCombine in class LeftAssociativeOperatorExpression

Tags copied from class: LeftAssociativeOperatorExpression

Parameters:

operator - is the Token between expressions (e.g., +,-,*,/,...)

accumResult - is result of accumulating the expressions to the left of the operator.

nextResult - is result of evaluating the next expression to the right of the operator.

Returns:

result of the combining accumResult and nextResult with operator

Throws:

ThrowException - if expression completes abruptly with exception
