Method Summary

Modifier and Type	Method	Description
boolean	equals(Object theO)
Boolean	getMissing()	If set to non-null value, indicates that this parameter has been populated with a "[name]:missing=true" or "[name]:missing=false" vale instead of a normal value
final String	getQueryParameterQualifier()	This method will return any qualifier that should be appended to the parameter name (e.g ":exact").
final String	getValueAsQueryToken()	Returns a representation of this parameter's value as it will be represented "over the wire".
int	hashCode()
boolean	isEmpty()	Returns true if this parameter has a null or empty getValueAsQueryToken() value, and doesn't have a getMissing() value.
protected boolean	isSupportsChain()	Does this parameter type support chained parameters (only reference should return true for this)
BaseParam	setMissing(Boolean theMissing)	If set to non-null value, indicates that this parameter has been populated with a "[name]:missing=true" or "[name]:missing=false" value instead of a normal value
final void	setValueAsQueryToken(FhirContext theContext, String theParamName, String theQualifier, String theValue)	This method is generally only called by HAPI itself, and should not need to be called from user code.

Method Details

getMissing

public Boolean getMissing()

If set to non-null value, indicates that this parameter has been populated with a "[name]:missing=true" or "[name]:missing=false" vale instead of a normal value

Specified by:

getMissing in interface IQueryParameterType

setMissing

public BaseParam setMissing(Boolean theMissing)

If set to non-null value, indicates that this parameter has been populated with a "[name]:missing=true" or "[name]:missing=false" value instead of a normal value

Specified by:

setMissing in interface IQueryParameterType

Returns:

Returns a reference to this for easier method chaining

getQueryParameterQualifier

public final String getQueryParameterQualifier()

Description copied from interface: IQueryParameterType

This method will return any qualifier that should be appended to the parameter name (e.g ":exact"). Returns null if none are present.

Specified by:

getQueryParameterQualifier in interface IQueryParameterType

getValueAsQueryToken

public final String getValueAsQueryToken()

Description copied from interface: IQueryParameterType

Returns a representation of this parameter's value as it will be represented "over the wire". In other words, how it will be presented in a URL (although not URL escaped)

See FHIR specification 2.2.2 Search SearchParameter Types for information on the token format

Specified by:

getValueAsQueryToken in interface IQueryParameterType

Returns:

Returns a representation of this parameter's value as it will be represented "over the wire". In other words, how it will be presented in a URL (although not URL escaped)

isSupportsChain

protected boolean isSupportsChain()

Does this parameter type support chained parameters (only reference should return true for this)

setValueAsQueryToken

public final void setValueAsQueryToken(FhirContext theContext,
 String theParamName,
 String theQualifier,
 String theValue)

Description copied from interface: IQueryParameterType

This method is generally only called by HAPI itself, and should not need to be called from user code.

See FHIR specification 2.2.2 Search SearchParameter Types for information on the token format

Specified by:

setValueAsQueryToken in interface IQueryParameterType

Parameters:

theContext - TODO

theParamName - TODO

theQualifier - The parameter name qualifier that accompanied this value. For example, if the complete query was http://foo?name:exact=John, qualifier would be ":exact"

theValue - The actual parameter value. For example, if the complete query was http://foo?name:exact=John, the value would be "John"

isEmpty

public boolean isEmpty()

Returns true if this parameter has a null or empty getValueAsQueryToken() value, and doesn't have a getMissing() value.

Specified by:

isEmpty in interface IQueryParameterType

Since:

8.4.0

equals

public boolean equals(Object theO)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
