Class BytecodeConfig

java.lang.Object

com.oracle.truffle.api.bytecode.BytecodeConfig

public final class BytecodeConfig
extends Object

The configuration to use while generating bytecode. The configuration determines what optional information (source sections, instrumentation instructions, etc.) should be materialized during parsing. The interpreter memory footprint can be improved by omitting this information by default and lazily re-parsing it when it is needed.

Instances of this class should be stored as static final constants. It is important for them to be constant so partial evaluation can detect when reparsing is unnecessary.

Method Details

newBuilder

public static BytecodeConfig.Builder newBuilder(BytecodeConfigEncoder encoder)

Produces a new BytecodeConfig.Builder that can be used to programmatically build a BytecodeConfig.

Note this method is not intended to be used directly. Use the generated method, for example MyBytecodeRootNodeGen.newConfigBuilder() instead.
