Detailed Description
SAX-style JSON parser. Use Reader for UTF8 encoding and default allocator.
GenericReader parses JSON text from a stream, and send events synchronously to an object implementing Handler concept.
It needs to allocate a stack for storing a single decoded string during non-destructive parsing.
For in-situ parsing, the decoded string is directly written to the source text string, no temporary buffer is required.
A GenericReader object can be reused for parsing multiple JSON text.
Parameters:
| SourceEncoding | Encoding of the input stream. |
| TargetEncoding | Encoding of the parse output. |
Allocator type for stack. |

Parameters:
| allocator | Optional allocator for allocating stack memory. (Only use for non-destructive parsing) |
| stackCapacity | stack capacity in bytes for storing a single decoded string. (Only use for non-destructive parsing) |

Parse(InputStream & is, Handler & handler)
Parse JSON text.
Parameters:
| parseFlags | Combination of ParseFlag. |
| InputStream | Type of input stream. |
Type of handler which must implement Handler concept. |
| stream | Input stream to be parsed. |
| handler | The handler to receive events. |
