getKind

public Node.ExpressionKind getKind()

Specified by:

getKind in class Expression

• Node.ExpressionKind

accept

public boolean accept(@Nonnull
 TreeVisitor visitor)

Description copied from class: Node

Visit this AST with a given visitor.

Specified by:

accept in class Node

Returns:

true to stop recursion and propagate true up the stack, false to continue

isLiteral

public boolean isLiteral()

Overrides:

isLiteral in class Expression

getFloatValue

public float getFloatValue()

getIntegerValue

public long getIntegerValue()

getBooleanValue

public boolean getBooleanValue()

getValue

public double getValue()

getConstantValue

public OptionalDouble getConstantValue(int i)

Description copied from class: Expression

Returns the i'th compile-time constant value within a literal or constructor. Indices which do not contain compile-time constant values will return empty. `vec4(1, vec2(2), 3)` contains four compile-time constants: (1, 2, 2, 3) `mat2(f)` contains four slots, and two are constant: (empty, 0, 0, empty)

Overrides:

getConstantValue in class Expression

clone

@Nonnull
public Expression clone(int position)

Specified by:

clone in class Expression

toString

@Nonnull
public String toString(int parentPrecedence)

Specified by:

toString in class Expression
