Method Detail

stringConstant

static java.lang.String stringConstant(int strIdx)

WASM code

Get a constant string from the table.

Parameters:

strIdx - the id/index of the string.

Returns:

the string

getStringFromTable

private static java.lang.String getStringFromTable(int strIdx)

WASM code

Get a string from the string table. Should be inlined from the optimizer.

Parameters:

strIdx - the id/index of the string.

Returns:

the string or null if not already set.

setStringIntoTable

private static void setStringIntoTable(int strIdx,
                                       java.lang.String str)

WASM code

Set a string in the string table. Should be inlined from the optimizer.

Parameters:

strIdx - the id/index of the string.

str - the string

stringsMemoryOffset

private static int stringsMemoryOffset()

WASM code

Placeholder for a synthetic function. Should be inlined from the optimizer.

Returns:

the memory offset of the serialized string data in the element section

getIntFromMemory

private static int getIntFromMemory(int pos)

WASM code

Load an i32 from memory. The offset must be aligned. Should be inlined from the optimizer.

Parameters:

pos - the memory position

Returns:

the value from the memory

getUnsignedByteFromMemory

private static byte getUnsignedByteFromMemory(int pos)

WASM code

Load a byte from the memory. Should be inlined from the optimizer.

Parameters:

pos - the memory position

Returns:

the value from the memory
