panda3d.core.StreamReader¶
from panda3d.core import StreamReader
-
class
StreamReader¶ A class to read sequential binary data directly from an istream. Its interface is similar to DatagramIterator by design; see also StreamWriter.
Inheritance diagram
-
__init__(copy: StreamReader) → None¶ The copy constructor does not copy ownership of the stream.
-
__init__(in: istream, owns_stream: bool) → None If owns_stream is true, the stream pointer will be deleted when the StreamReader destructs.
-
assign(copy: StreamReader) → StreamReader¶ - Return type
-
getBool() → bool¶ Extracts a boolean value.
-
getInt8() → int8_t¶ Extracts a signed 8-bit integer.
- Return type
int8_t
-
getUint8() → uint8_t¶ Extracts an unsigned 8-bit integer.
- Return type
uint8_t
-
getInt16() → int16_t¶ Extracts a signed 16-bit integer.
- Return type
int16_t
-
getInt32() → int32_t¶ Extracts a signed 32-bit integer.
- Return type
int32_t
-
getInt64() → int64_t¶ Extracts a signed 64-bit integer.
- Return type
int64_t
-
getUint16() → uint16_t¶ Extracts an unsigned 16-bit integer.
- Return type
uint16_t
-
getUint32() → uint32_t¶ Extracts an unsigned 32-bit integer.
- Return type
uint32_t
-
getUint64() → uint64_t¶ Extracts an unsigned 64-bit integer.
- Return type
uint64_t
-
getFloat32() → float¶ Extracts a 32-bit single-precision floating-point number. Since this kind of float is not necessarily portable across different architectures, special care is required.
-
getFloat64() → PN_float64¶ Extracts a 64-bit floating-point number.
- Return type
PN_float64
-
getBeInt16() → int16_t¶ Extracts a signed big-endian 16-bit integer.
- Return type
int16_t
-
getBeInt32() → int32_t¶ Extracts a signed big-endian 32-bit integer.
- Return type
int32_t
-
getBeInt64() → int64_t¶ Extracts a signed big-endian 64-bit integer.
- Return type
int64_t
-
getBeUint16() → uint16_t¶ Extracts an unsigned big-endian 16-bit integer.
- Return type
uint16_t
-
getBeUint32() → uint32_t¶ Extracts an unsigned big-endian 32-bit integer.
- Return type
uint32_t
-
getBeUint64() → uint64_t¶ Extracts an unsigned big-endian 64-bit integer.
- Return type
uint64_t
-
getBeFloat32() → float¶ Extracts a 32-bit single-precision big-endian floating-point number. Since this kind of float is not necessarily portable across different architectures, special care is required.
-
getBeFloat64() → PN_float64¶ Extracts a 64-bit big-endian floating-point number.
- Return type
PN_float64
-
getString() → str¶ Extracts a variable-length string.
-
getString32() → str¶ Extracts a variable-length string with a 32-bit length field.
-
getZString() → str¶ Extracts a variable-length string, as a NULL-terminated string.
-
getFixedString(size: size_t) → str¶ Extracts a fixed-length string. However, if a zero byte occurs within the string, it marks the end of the string.
-
skipBytes(size: size_t) → None¶ Skips over the indicated number of bytes in the stream.
-
extractBytes(size: size_t) → object¶ Extracts the indicated number of bytes in the stream and returns them as a string. Returns empty string at end-of-file.
-
readline() → object¶ Assumes the stream represents a text file, and extracts one line up to and including the trailing newline character. Returns empty string when the end of file is reached.
The interface here is intentionally designed to be similar to that for Python’s File.readline() function.
