AcdFunResolve

public AcdFunResolve(java.lang.String exp)

Parameters:

exp - String with possible expression to expand

Method Detail

getResult

public java.lang.String getResult()

Returns the value of the result of the expression.

Returns:

result

acdFunResolve

public java.lang.String acdFunResolve(java.lang.String var)

Looks for and resolves expressions

Returns:

result

acdExpPlus

private boolean acdExpPlus(java.lang.String exp)

Looks for and resolves an expression @( num + num )

Parameters:

exp - String with possible expression

Returns:

true if successfully resolved

acdExpMinus

private boolean acdExpMinus(java.lang.String exp)

Looks for and resolves an expression @( num - num )

Parameters:

exp - String with possible expression

Returns:

true if successfully resolved

acdExpStar

private boolean acdExpStar(java.lang.String exp)

Looks for and resolves an expression @( num * num )

Parameters:

exp - String with possible expression

Returns:

true if successfully resolved

acdExpDiv

private boolean acdExpDiv(java.lang.String exp)

Looks for and resolves an expression @( num * num )

Looks for and resolves an expression @( num != num )

Parameters:

exp - String with possible expression

Returns:

true if successfully resolved
