Method Details

convert

@Nullable
public static Expression convert(@Nonnull
 Context context,
 int position,
 @Nonnull
 Expression base,
 int maskPosition,
 @Nonnull
 String maskString)

Create swizzle expressions. This method permits components containing ZERO or ONE, does typechecking, reports errors via ErrorHandler, and returns an expression that combines constructors and native swizzles (comprised solely of X/Y/W/Z).

make

@Nonnull
public static Expression make(@Nonnull
 Context context,
 int position,
 @Nonnull
 Expression base,
 byte[] components,
 int numComponents)

getKind

public Node.ExpressionKind getKind()

Specified by:

getKind in class Expression

See Also:

• 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

getBase

public Expression getBase()

getComponents

public byte[] getComponents()

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
