panda3d.core.HashVal¶

from panda3d.core import HashVal

class HashVal¶

Stores a 128-bit value that represents the hashed contents (typically MD5) of a file or buffer.

Inheritance diagram

__init__() → None¶

__init__(copy: HashVal) → None

assign(copy: HashVal) → HashVal¶

Return type: HashVal

compareTo(other: HashVal) → int¶

mergeWith(other: HashVal) → None¶: Generates a new HashVal representing the xor of this one and the other one.

outputDec(out: ostream) → None¶: Outputs the HashVal as four unsigned decimal integers.

inputDec(in: istream) → None¶: Inputs the HashVal as four unsigned decimal integers.

outputHex(out: ostream) → None¶: Outputs the HashVal as a 32-digit hexadecimal number.

inputHex(in: istream) → None¶: Inputs the HashVal as a 32-digit hexadecimal number.

outputBinary(out: ostream) → None¶: Outputs the HashVal as a binary stream of bytes in order. This is not the same order generated by writeStream().

inputBinary(in: istream) → None¶: Inputs the HashVal as a binary stream of bytes in order. This is not the same order expected by readStream().

output(out: ostream) → None¶

asDec() → str¶: Returns the HashVal as a string with four decimal numbers.

setFromDec(text: str) → bool¶: Sets the HashVal from a string with four decimal numbers. Returns true if valid, false otherwise.

asHex() → str¶: Returns the HashVal as a 32-byte hexadecimal string.

setFromHex(text: str) → bool¶: Sets the HashVal from a 32-byte hexademical string. Returns true if successful, false otherwise.

asBin() → bytes¶: Returns the HashVal as a 16-byte binary string.

setFromBin(text: bytes) → bool¶: Sets the HashVal from a 16-byte binary string. Returns true if successful, false otherwise.

writeDatagram(destination: Datagram) → None¶

readDatagram(source: DatagramIterator) → None¶

writeStream(destination: StreamWriter) → None¶

readStream(source: StreamReader) → None¶

hashFile(filename: Filename) → bool¶: Generates the hash value from the indicated file. Returns true on success, false if the file cannot be read. This method is only defined if we have the OpenSSL library (which provides md5 functionality) available.

hashStream(stream: istream) → bool¶: Generates the hash value from the indicated file. Returns true on success, false if the file cannot be read. This method is only defined if we have the OpenSSL library (which provides md5 functionality) available.

hashRamfile(ramfile: Ramfile) → None¶: Generates the hash value by hashing the indicated data. This method is only defined if we have the OpenSSL library (which provides md5 functionality) available.

hashString(data: str) → None¶: Generates the hash value by hashing the indicated data. This method is only defined if we have the OpenSSL library (which provides md5 functionality) available.

hashBytes(data: bytes) → None¶: Generates the hash value by hashing the indicated data. This method is only defined if we have the OpenSSL library (which provides md5 functionality) available.

hashBuffer(buffer: str, length: int) → None¶: Generates the hash value by hashing the indicated data. This method is only defined if we have the OpenSSL library (which provides md5 functionality) available.
