Constructor Details

WasmOptions

public WasmOptions(HashMap<String,String> properties)

Create a new instance of options

Parameters:

properties - compiler properties

Method Details

debugNames

public boolean debugNames()

Property for adding debug names to the output if true.

Returns:

true, add debug information

useGC

public boolean useGC()

If the GC feature of WASM should be use or the GC of the JavaScript host.

Returns:

true, use the GC instructions of WASM.

useEH

public boolean useEH()

If the exception handling feature of WASM should be use or an unreachable instruction.

Returns:

true, use the EH instructions of WASM; false, generate an unreachable instruction

getSourceMapBase

@Nonnull
public String getSourceMapBase()

Get the relative path between the final wasm file location and the source files location. If not empty it should end with a slash like "../../src/main/java/".
