Constructor Detail

MergeDocument

public MergeDocument(Document document1,
                     Document document2)

Create a document that contains all of the fields from the two documents, with the first document taking precedence.

Parameters:

document1 - the first (preceding) document; may not be null

document2 - the second document; may not be null

MergeDocument

public MergeDocument(Document document1,
                     Document document2,
                     Document document3)

Create a document that contains all of the fields from the three documents, with the first document taking precedence over the others, and the second taking precedence over the third.

Parameters:

document1 - the first (preceding) document; may not be null

document2 - the second document; may not be null

document3 - the third document; may not be null

Method Detail

clone

public MergeDocument clone()

Description copied from interface: Document

Obtain a clone of this document.

Specified by:

clone in interface Document

Overrides:

clone in class Object

Returns:

the clone of this document; never null

with

public MergeDocument with(Map<String,Object> changedFields)

Description copied from interface: Document

Obtain a clone of this document, but with the supplied fields replaced.

Specified by:

with in interface Document

Parameters:

changedFields - the fields that should be changed; may be null

Returns:

the clone of this document with the change fields, or this document if there are no changes

with

public Document with(Document.ValueTransformer transformer)

Description copied from interface: Document

Obtain a clone of this document, but with the field values transformed using the supplied Document.ValueTransformer.

Specified by:

with in interface Document

Parameters:

transformer - the transformer that should be used to transform each field value; may not be null

Returns:

the clone of this document with transformed fields, or this document if the transformer changed none of the values

withVariablesReplaced

public Document withVariablesReplaced(Properties properties)

Description copied from interface: Document

Obtain a clone of this document, but with all variables in string field values replaced with the referenced values from the supplied properties.

Variables may appear anywhere within a string value, and multiple variables can be used within the same value. Variables take the form:

    variable := '${' variableNames [ ':' defaultValue ] '}'
    
    variableNames := variableName [ ',' variableNames ]
    
    variableName := /* any characters except ',' and ':' and '}'
    
    defaultValue := /* any characters except
 

Note that variableName is the name used to look up the Properties property.

Notice that the syntax supports multiple variables. The logic will process the variables from let to right, until an existing System property is found. And at that point, it will stop and will not attempt to find values for the other variables.

Specified by:

withVariablesReplaced in interface Document

Parameters:

properties - the properties keyed by variable name

Returns:

the clone of this document with variables in fields string values replaced with values from the properties object, or this document if no variables were found

See Also:

Document.withVariablesReplacedWithSystemProperties(), Document.with(ValueTransformer), SchemaLibrary.convertValues(Document, String)

withVariablesReplacedWithSystemProperties

public Document withVariablesReplacedWithSystemProperties()

Description copied from interface: Document

Obtain a clone of this document, but with all variables in string field values replaced with the referenced values from the System properties.

Variables may appear anywhere within a string value, and multiple variables can be used within the same value. Variables take the form:

    variable := '${' variableNames [ ':' defaultValue ] '}'
    
    variableNames := variableName [ ',' variableNames ]
    
    variableName := /* any characters except ',' and ':' and '}'
    
    defaultValue := /* any characters except
 

Note that variableName is the name used to look up a System property via System.getProperty(String).

Notice that the syntax supports multiple variables. The logic will process the variables from let to right, until an existing System property is found. And at that point, it will stop and will not attempt to find values for the other variables.

Because only string values can contain variables, the resulting values are left as strings. This may not be valid according to the document's JSON Schema, so see SchemaLibrary.convertValues(Document, String) to convert the string values after variable substitution into the expected non-string types.

Specified by:

withVariablesReplacedWithSystemProperties in interface Document

Returns:

the clone of this document with variables in fields string values replaced with values from the System properties, or this document if no variables were found
