Class SnippetTemplate.Arguments

java.lang.Object

com.oracle.graal.replacements.SnippetTemplate.Arguments

All Implemented Interfaces:

Formattable

Enclosing class:

SnippetTemplate

public static class SnippetTemplate.Arguments
extends Object
implements Formattable

Values that are bound to the snippet method parameters. The methods add(java.lang.String, java.lang.Object), addConst(java.lang.String, java.lang.Object), and addVarargs(java.lang.String, java.lang.Class<?>, com.oracle.graal.compiler.common.type.Stamp, java.lang.Object) must be called in the same order as in the signature of the snippet method. The parameter name is passed to the add methods for assertion checking, i.e., to enforce that the order matches. Which method needs to be called depends on the annotation of the snippet method parameter:

• Use add(java.lang.String, java.lang.Object) for a parameter without an annotation. The value is bound when the SnippetTemplate is instantiated.
• Use addConst(java.lang.String, java.lang.Object) for a parameter annotated with Snippet.ConstantParameter. The value is bound when the SnippetTemplate is created.
• Use addVarargs(java.lang.String, java.lang.Class<?>, com.oracle.graal.compiler.common.type.Stamp, java.lang.Object) for an array parameter annotated with Snippet.VarargsParameter. A separate SnippetTemplate is created for every distinct array length. The actual values are bound when the SnippetTemplate is instantiated
