|
| ezStreamReader () |
| | Constructor.
|
| |
|
virtual | ~ezStreamReader () |
| | Virtual destructor to ensure correct cleanup.
|
| |
|
virtual ezUInt64 | ReadBytes (void *pReadBuffer, ezUInt64 uiBytesToRead)=0 |
| | Reads a raw number of bytes into the read buffer, this is the only method which has to be implemented to fully implement the interface.
|
| |
|
template<typename T > |
| ezResult | ReadWordValue (T *pWordValue) |
| | Helper method to read a word value correctly (copes with potentially different endianess)
|
| |
|
template<typename T > |
| ezResult | ReadDWordValue (T *pDWordValue) |
| | Helper method to read a dword value correctly (copes with potentially different endianess)
|
| |
|
template<typename T > |
| ezResult | ReadQWordValue (T *pQWordValue) |
| | Helper method to read a qword value correctly (copes with potentially different endianess)
|
| |
|
template<typename ArrayType , typename ValueType > |
| ezResult | ReadArray (ezArrayBase< ValueType, ArrayType > &inout_array) |
| | Reads an array of elements from the stream.
|
| |
|
template<typename ValueType , ezUInt16 uiSize, typename AllocatorWrapper > |
| ezResult | ReadArray (ezSmallArray< ValueType, uiSize, AllocatorWrapper > &ref_array) |
| | Reads a small array of elements from the stream.
|
| |
|
template<typename ValueType , ezUInt32 uiSize> |
| ezResult | ReadArray (ValueType(&array)[uiSize]) |
| | Writes a C style fixed array.
|
| |
|
template<typename KeyType , typename Comparer > |
| ezResult | ReadSet (ezSetBase< KeyType, Comparer > &inout_set) |
| | Reads a set.
|
| |
|
template<typename KeyType , typename ValueType , typename Comparer > |
| ezResult | ReadMap (ezMapBase< KeyType, ValueType, Comparer > &inout_map) |
| | Reads a map.
|
| |
|
template<typename KeyType , typename ValueType , typename Hasher > |
| ezResult | ReadHashTable (ezHashTableBase< KeyType, ValueType, Hasher > &inout_hashTable) |
| | Read a hash table (note that the entry order is not stable)
|
| |
|
ezResult | ReadString (ezStringBuilder &ref_sBuilder) |
| | Reads a string into an ezStringBuilder.
|
| |
|
ezResult | ReadString (ezString &ref_sString) |
| | Reads a string into an ezString.
|
| |
|
virtual ezUInt64 | SkipBytes (ezUInt64 uiBytesToSkip) |
| | Helper method to skip a number of bytes (implementations of the stream reader may implement this more efficiently for example)
|
| |
|
EZ_ALWAYS_INLINE ezTypeVersion | ReadVersion (ezTypeVersion expectedMaxVersion) |
| |
The base class for all file readers. Provides access to ezFileSystem::GetFileReader, which is necessary to get access to the streams that ezDataDirectoryType's provide. Derive from this class if you want to implement different policies on how to read files. E.g. the default reader (ezFileReader) implements a buffered read policy (using an internal cache).
