Default constructor.

Method Detail

getMetadata

public Metadata getMetadata()

Returns the metadata associated with this projection (who generated or last changed it, and when). Declared directly here, not inherited from IdentifiableElement, since a TypeProjection has no id of its own.

Specified by:

getMetadata in interface TypeProjection

Returns:

the metadata

setMetadata

public void setMetadata(Metadata metadata)

Sets the metadata associated with this projection.

Specified by:

setMetadata in interface TypeProjection

Parameters:

metadata - the metadata

getQueryAsString

public String getQueryAsString()
                        throws org.gcube.com.fasterxml.jackson.core.JsonProcessingException

Returns the query body as a string.

Specified by:

getQueryAsString in interface TypeProjection

Returns:

the query as a string

Throws:

org.gcube.com.fasterxml.jackson.core.JsonProcessingException - if an error occurs during serialization

setQuery

public void setQuery(String query)
              throws org.gcube.com.fasterxml.jackson.core.JsonProcessingException,
                     IOException

Sets the query body from a string.

Specified by:

setQuery in interface TypeProjection

Parameters:

query - the query as a string

Throws:

org.gcube.com.fasterxml.jackson.core.JsonProcessingException - if an error occurs during JSON processing

IOException - if an error occurs during parsing

getQuery

public org.gcube.com.fasterxml.jackson.databind.JsonNode getQuery()

Returns the query body as a JsonNode.

Specified by:

getQuery in interface TypeProjection

Returns:

the query as a JsonNode

setQuery

public void setQuery(org.gcube.com.fasterxml.jackson.databind.JsonNode query)

Sets the query body from a JsonNode.

Deliberately typed as JsonNode, not a polymorphic Element reference — the query's content embeds its own "type" (e.g. "EService"), which describes what it queries, not a real instance to deserialize. Typing it as a plain JsonNode keeps Element's @JsonTypeInfo-driven polymorphic resolution from being triggered on that embedded discriminator — the exact same reason QueryTemplate.setTemplate(JsonNode) is typed the same way.

Specified by:

setQuery in interface TypeProjection

Parameters:

query - the query as a JsonNode

getDescription

public String getDescription()

Returns the description of this projection — which fields/columns it returns and why.

Specified by:

getDescription in interface TypeProjection

Returns:

the description

setDescription

public void setDescription(String description)

Sets the description of this projection.

Specified by:

setDescription in interface TypeProjection

Parameters:

description - the description

getSource

public TypeProjection.Source getSource()

Returns whether this projection is TypeProjection.Source.AUTO_GENERATED or TypeProjection.Source.CUSTOM. Never client-submittable: assigned by the server depending on whether the owning Type has an admin-defined projection.

Specified by:

getSource in interface TypeProjection

Returns:

the source

setSource

public void setSource(TypeProjection.Source source)

Sets the source of this projection.

Specified by:

setSource in interface TypeProjection

Parameters:

source - the source
