Method Details

evaluateConstant

public <T> ResultOrProblems<T> evaluateConstant(RealizationContext context,
 Class<T> requiredJavaType,
 Type requiredType)

Attempts to realize and evaluate this argument against an empty Struct, returning useful problems if the expression wasn't constant or if the returned type doesn't match the expected java type.

ExpressionRealizer.realizeConstant(Expression) has more details.

Type Parameters:

T - the expected object

Parameters:

requiredJavaType - the java type that we expect the expression to yield. Checked against the expression's return type, not the actual constant value's class type.

requiredType - a riskscape type to use in any error message that's generated

getExpression

@Deprecated
public Expression getExpression()

Deprecated.

use getValue() instead.

appendSource

protected static void appendSource(AST ast,
 StringBuilder appendTo)

Helper method for appending the source of another ast element to a string builder, efficiently if possible.

toString

public final String toString()

Returns a simplified view of the ast in a source-like fashion, but with a lot of details left out for conciseness

Overrides:

toString in class Object

appendString

protected void appendString(StringBuilder appendTo)

Append a simplified string representation to the builder. Default implementation uses appendSource. Subclasses can override to provide a more concise representation.

toSource

public final String toSource()

Specified by:

toSource in interface AST

Returns:

a normalized version of the AST that can be parsed to be exactly the same AST as this
