EMethods

A collection of methods that operate on Expression nodes.

class EMethods {

Diagnostics diag;

this(Diagnostics diag = null);

void error(Node n, cstring msg, ...);

long toInt(Expression e);

ulong toUInt(Expression e);

void errorExpectedIntOrFloat(Expression e);

Float toImag(Expression e);

Float toReal(Expression e);

Complex toComplex(Expression e);

static bool isConst(Expression e);

static int isBool(Expression e);

static bool isTrue(Expression e);

static bool isFalse(Expression e);

static Expression toBool(Expression e);

Float toRealOrImag(Expression e);

static Expression arrayLength(Expression e);

Expression toLValue(Expression e);

Expression addressOf(Expression e);

}

Constructors

this this(Diagnostics diag = null): Constructs an EMethods object.

Members

Functions

addressOf Expression addressOf(Expression e): Returns the expression &e.
error void error(Node n, cstring msg, ...): Issues an error.
errorExpectedIntOrFloat void errorExpectedIntOrFloat(Expression e): Reports an error.
toComplex Complex toComplex(Expression e): Returns Re(e) + Im(e).
toImag Float toImag(Expression e): Returns Im(e).
toInt long toInt(Expression e): Converts the expression to an integer. Reports an error if impossible.
toLValue Expression toLValue(Expression e): Returns the lvalue of e.
toReal Float toReal(Expression e): Returns Re(e).
toRealOrImag Float toRealOrImag(Expression e): Returns the Float value of e.
toUInt ulong toUInt(Expression e): Converts the expression to an integer. Reports an error if impossible.

Static functions

arrayLength Expression arrayLength(Expression e): Returns the length of a string/array/assocarray.
isBool int isBool(Expression e): Checks if e has a boolean value.
isConst bool isConst(Expression e): Returns true if e is a constant expression.
isFalse bool isFalse(Expression e): Returns true if e has a boolean value and if it is false.
isTrue bool isTrue(Expression e): Returns true if e has a boolean value and if it is true.
toBool Expression toBool(Expression e): Returns a boolean IntExpr if e has a boolean value, otherwise NAR.

Variables
