Class YamlObject<T>

Object

YamlObject<T>

Direct Known Subclasses:

YamlMap, YamlSeq

public class YamlObject<T>
extends Object

Base class for Yaml object wrappers.

Yaml is represented as atomic types (literals, expressions) and YamlObjects (for wrapping lists and maps). The factory method create(Object) will sort out the details. These YamlObjects are used to stage data when parsing a Yaml document.

Method Detail

create

public static <W> YamlObject<W> create(W raw)

Convert raw object to Yaml wrapper.

• Map wrapped as YamlMap
• List wrapped as YamlSeq

Other data (Literals, Expressions) are considered atomic and do not provide a YamlObject representation.

Parameters:

raw -

Returns:

Yaml object wrapper, or null if the provided raw object is null.

map

public YamlMap map()

Casts this object to a YamlMap.

seq

public YamlSeq seq()

Casts this object to a YamlSeq.

lookup

public Object lookup(String path)

Raw value access via path.

Indended for quick value lookup during test cases.

• raw("1"): first value in a sequence
• raw("x"): value for "x" in a map
• raw("rules/2/symbolizers/3"): third symbolizer in second rule

Parameters:

path -

Returns:

raw value, or null if not available

raw

public T raw()

Returns the raw object.

lookupY

public Object lookupY(String path)

See lookup(java.lang.String). Ensures that the result is wrapped as a YamlObject if it is a map, list, or array.

Parameters:

path -

convert

protected <C> C convert(Object obj,
                        Class<C> clazz)

Converts an object to the specified class.

toString

public String toString()

Yaml representation.

Overrides:

toString in class Object

Returns:

Yaml representation
