Method Detail

matches

public boolean matches(UnmarshallingContext context)

Description copied from interface: Parser

Returns whether this parser and its children match a record being unmarshalled.

Specified by:

matches in interface Parser

Overrides:

matches in class DelegatingParser

Parameters:

context - the UnmarshallingContext

Returns:

true if matched, false otherwise

unmarshal

public boolean unmarshal(UnmarshallingContext context)

Description copied from interface: Parser

Unmarshals a record.

Specified by:

unmarshal in interface Parser

Overrides:

unmarshal in class DelegatingParser

Parameters:

context - the UnmarshallingContext

Returns:

true if this component was present in the unmarshalled record, or false otherwise

marshal

public boolean marshal(MarshallingContext context)
                throws IOException

Description copied from interface: Parser

Marshals a record.

Specified by:

marshal in interface Parser

Overrides:

marshal in class DelegatingParser

Parameters:

context - the MarshallingContext

Returns:

whether a value was marshalled

Throws:

IOException - if an I/O error occurs

getJsonName

public String getJsonName()

Description copied from interface: JsonNode

Returns the JSON field name.

Specified by:

getJsonName in interface JsonNode

Returns:

the JSON field name

setJsonName

public void setJsonName(String jsonName)

getJsonType

public char getJsonType()

Description copied from interface: JsonNode

Returns the type of node. If JsonNode.isJsonArray() is true, this method returns the component type of the array.

Specified by:

getJsonType in interface JsonNode

Returns:

the node type

setJsonType

public void setJsonType(char jsonType)

isJsonArray

public boolean isJsonArray()

Description copied from interface: JsonNode

Returns whether this node is a JSON array.

Specified by:

isJsonArray in interface JsonNode

Returns:

true if this node a JSON array, false otherwise

setJsonArray

public void setJsonArray(boolean jsonArray)

getJsonArrayIndex

public int getJsonArrayIndex()

Description copied from interface: JsonNode

Returns the index of this node in its parent array, or -1 if not applicable (i.e. its parent is an object).

Specified by:

getJsonArrayIndex in interface JsonNode

Returns:

the index of this node in its parent array

setJsonArrayIndex

public void setJsonArrayIndex(int jsonArrayIndex)

isNillable

public boolean isNillable()

Description copied from interface: JsonNode

Returns whether this node may be explicitly set to null.

Specified by:

isNillable in interface JsonNode

Returns:

true if this node value may be set to null, false otherwise

setNillable

public void setNillable(boolean nillable)

isLazy

public boolean isLazy()

Description copied from interface: Parser

Returns whether this node must exist during unmarshalling.

Specified by:

isLazy in interface Parser

Overrides:

isLazy in class DelegatingParser

Returns:

true if this node is optional during unmarshalling, false otherwise

setLazy

public void setLazy(boolean lazy)

Parameters:

lazy -

toParamString

protected void toParamString(StringBuilder s)

Description copied from class: TreeNode

Called by TreeNode.toString() to append node parameters to the output.

Overrides:

toParamString in class TreeNode<Component>

Parameters:

s - the output to append
