Class ArrayToMap

java.lang.Object

hlt.language.design.kernel.Expression

hlt.language.design.kernel.ProtoExpression

hlt.language.design.kernel.ArrayToMap

All Implemented Interfaces:

Locatable

public class ArrayToMap
extends ProtoExpression

This constructs enables the conversion from a (possibly mutidimensional) array to a indexed map as long as the base type and the number of dimensions agree.

Methods

Modifier and Type	Method and Description
Expression	array()
void	compile(Compiler compiler) This method compiles this expression in the context of the specified Compiler.
Expression	copy() Returns a deep copy of this expression.
Expression	indexable()
int	numberOfSubexpressions() Returns the number of subexpressions
void	setCheckedType() This method sets the final unambiguously checked type of this expression, possibly along with other final information that may be needed by the compiler for generating code.
Expression	setSubexpression(int n, Expression expression) Returns this expression after setting its n-th subexpression to the specified expression; if there is no subexpression at the given position, this throws a NoSuchSubexpressionException
Expression	subexpression(int n) Returns the n-th subexpression of this expression; if there is no subexpression at the given position, this throws a NoSuchSubexpressionException
java.lang.String	toString()
void	typeCheck(TypeChecker typeChecker) This method type-checks this expression in the context of the specified TypeChecker.
Expression	typedCopy() Returns a deep copy of this expression this and all its subexpressions share the same type as their copy's counterparts.

Method Detail

copy

public final Expression copy()

Description copied from class: Expression

Returns a deep copy of this expression. The types are not not copied. NB: This is a convenience for building expressions that should be used exclusively before any processing (in particular sanitizing), is done on this expression.

Specified by:

copy in class Expression

typedCopy

public final Expression typedCopy()

Description copied from class: Expression

Returns a deep copy of this expression this and all its subexpressions share the same type as their copy's counterparts. NB: This is a convenience for building expressions that should be used exclusively before any processing (in particular sanitizing), is done on this expression.

Specified by:

typedCopy in class Expression

numberOfSubexpressions

public final int numberOfSubexpressions()

Description copied from class: Expression

Returns the number of subexpressions

Overrides:

numberOfSubexpressions in class Expression

subexpression

public final Expression subexpression(int n)
                               throws NoSuchSubexpressionException

Description copied from class: Expression

Returns the n-th subexpression of this expression; if there is no subexpression at the given position, this throws a NoSuchSubexpressionException

Overrides:

subexpression in class Expression

Throws:

NoSuchSubexpressionException

setSubexpression

public final Expression setSubexpression(int n,
                          Expression expression)
                                  throws NoSuchSubexpressionException

Description copied from class: Expression

Returns this expression after setting its n-th subexpression to the specified expression; if there is no subexpression at the given position, this throws a NoSuchSubexpressionException

Overrides:

setSubexpression in class Expression

Throws:

NoSuchSubexpressionException

array

public final Expression array()

indexable

public final Expression indexable()

setCheckedType

public final void setCheckedType()

Description copied from class: Expression

This method sets the final unambiguously checked type of this expression, possibly along with other final information that may be needed by the compiler for generating code.

Specified by:

setCheckedType in class Expression

typeCheck

public final void typeCheck(TypeChecker typeChecker)
                     throws TypingErrorException

Description copied from class: Expression

This method type-checks this expression in the context of the specified TypeChecker.

Specified by:

typeCheck in class Expression

Throws:

TypingErrorException

compile

public final void compile(Compiler compiler)

Description copied from class: Expression

This method compiles this expression in the context of the specified Compiler.

Specified by:

compile in class Expression

toString

public final java.lang.String toString()

Overrides:

toString in class java.lang.Object
