Interface Parser.Config

Enclosing interface:

Parser

public static interface Parser.Config

Config describes the complete configuration of a Parser. Instances of Config are constructed by a Parser.Config.Builder, provided by Parsers.newParserConfigBuilder().

A Config provides two kinds of configuration:

1. One CollectionBuilder.Factory for building each of: lists, vectors, sets and maps.
2. A mapping of Tags to TagHandlers:
   • The tags #uuid and #inst, which are defined by edn, are provided with handlers by default.
   • The special tags BIG_DECIMAL_TAG, DOUBLE_TAG, BIG_INTEGER_TAG and LONG_TAG can be provided with TagHandlers to influence how numeric literals are represented by Parser.nextValue(Parseable).

Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static interface	Parser.Config.Builder This Builder is used to create a Parser.Config.

Field Summary

Fields

Modifier and Type	Field and Description
static Tag	BIG_DECIMAL_TAG Floating point literals which are marked by a trailing "M" are initially parsed as BigDecimal.
static Tag	BIG_INTEGER_TAG Integer literals marked by a trailing "N", and those not so marked which lie outside the range of a Long are initially parsed as BigInteger.
static Tag	DOUBLE_TAG Floating point literals not marked by a trailing "M" are initially parsed as Double.
static Tag	EDN_INSTANT This is the #inst tag specified by edn.
static Tag	EDN_UUID This is the #uuid tag specified by edn.
static Tag	LONG_TAG Integer literals which lie inside the range of a Long and are not marked by a trailing "N" are initially parsed as Long.

Method Summary

Methods

Modifier and Type	Method and Description
CollectionBuilder.Factory	getListFactory() Provide a CollectionBuilder.Factory to receive the contents of a list literal.
CollectionBuilder.Factory	getMapFactory() Provide a CollectionBuilder.Factory to receive the contents of a map literal.
CollectionBuilder.Factory	getSetFactory() Provide a CollectionBuilder.Factory to receive the contents of a set literal.
TagHandler	getTagHandler(Tag tag) Return the TagHandler associated with the given Tag, or null.
CollectionBuilder.Factory	getVectorFactory() Provide a CollectionBuilder.Factory to receive the contents of a vector literal.

Field Detail

EDN_UUID

static final Tag EDN_UUID

This is the #uuid tag specified by edn.

EDN_INSTANT

static final Tag EDN_INSTANT

This is the #inst tag specified by edn.

BIG_DECIMAL_TAG

static final Tag BIG_DECIMAL_TAG

Floating point literals which are marked by a trailing "M" are initially parsed as BigDecimal.

If you wish to customize the representation of decimal floating point literals, install a TagHandler for this Tag. The result of calling this handler with the parsed BigDecimal will be used in the value returned by the parser.

DOUBLE_TAG

static final Tag DOUBLE_TAG

Floating point literals not marked by a trailing "M" are initially parsed as Double.

Install a TagHandler for this tag if you wish to customize the representation of floating point literals. The result of calling this handler with the parsed Double will be used in the value returned by the parser.

BIG_INTEGER_TAG

static final Tag BIG_INTEGER_TAG

Integer literals marked by a trailing "N", and those not so marked which lie outside the range of a Long are initially parsed as BigInteger.

Install a TagHandler for this tag if you wish to customize the representation of big integer literals. The result of calling this handler with the parsed BigInteger will be used in the value returned by the parser.

LONG_TAG

static final Tag LONG_TAG

Integer literals which lie inside the range of a Long and are not marked by a trailing "N" are initially parsed as Long.

Install a TagHandler for this tag if you wish to customize the representation of long integer literals. The result of calling this handler with the parsed Long will be used in the value returned by the parser.

Method Detail

getListFactory

CollectionBuilder.Factory getListFactory()

Provide a CollectionBuilder.Factory to receive the contents of a list literal.

The default implementation returns an unmodifiable view of a List that does not implement RandomAccess.

Returns:

a CollectionBuilder.Factory for building lists; never null.

getVectorFactory

CollectionBuilder.Factory getVectorFactory()

Provide a CollectionBuilder.Factory to receive the contents of a vector literal.

The default implementation returns an unmodifiable view of a List that implements RandomAccess.

Returns:

a CollectionBuilder.Factory for building vectors; never null.

getSetFactory

CollectionBuilder.Factory getSetFactory()

Provide a CollectionBuilder.Factory to receive the contents of a set literal.

The default implementation returns an unmodifiable view of a Set (hashed, not sorted).

Returns:

a CollectionBuilder.Factory for building sets; never null.

getMapFactory

CollectionBuilder.Factory getMapFactory()

Provide a CollectionBuilder.Factory to receive the contents of a map literal.

The default implementation returns an unmodifiable view of a Map (hashed, not sorted).

Returns:

a CollectionBuilder.Factory for building maps; never null.

getTagHandler

TagHandler getTagHandler(Tag tag)

Return the TagHandler associated with the given Tag, or null.

Parameters:

tag - must not be null.

Returns:

TagHandler associated with tag, or null.
