ExtractorUtil

@Pure
java-static fun checkContainerInput(expression: Boolean, message: String?): Unit

If expression is false, throws a container malformed ParserException with the given message. Otherwise, does nothing.

java-static fun peekFullyQuietly(
    input: ExtractorInput!,
    output: ByteArray!,
    offset: Int,
    length: Int,
    allowEndOfInput: Boolean
): Boolean

Peeks data from input, respecting allowEndOfInput. Returns true if the peek is successful.

If allowEndOfInput=false then encountering the end of the input (whether before or after reading some data) will throw EOFException.

If allowEndOfInput=true then encountering the end of the input (even after reading some data) will return false.

This is slightly different to the behaviour of peekFully, where allowEndOfInput=true only returns false (and suppresses the exception) if the end of the input is reached before reading any data.

java-static fun peekToLength(
    input: ExtractorInput!,
    target: ByteArray!,
    offset: Int,
    length: Int
): Int

Peeks length bytes from the input peek position, or all the bytes to the end of the input if there was less than length bytes left.

If an exception is thrown, there is no guarantee on the peek position.

java-static fun readFullyQuietly(
    input: ExtractorInput!,
    output: ByteArray!,
    offset: Int,
    length: Int
): Boolean

Equivalent to readFully except that it returns false instead of throwing an EOFException if the end of input is encountered without having fully satisfied the read.

java-static fun skipFullyQuietly(input: ExtractorInput!, length: Int): Boolean

Equivalent to skipFully except that it returns false instead of throwing an EOFException if the end of input is encountered without having fully satisfied the skip.
